ADOLPHE BOURNIQUE, OF OHESTERTON, INDIANA, ASSIGNOR OF ONE-HALF TOCHARLES J. BOOKIUS, AOF SYRAOUSE, INDIANA, AND VILLIAM J. BORREY, OFFAIRMOUNT, INDIANA.

MACHINE FOR MANUFACTURING WINDOW-GLASS.

SPECIFICATION forming part of Letters Patent No. 771,763, dated October4, 1904.

Application filed November 16, 1903. Serial No.' 181,430. (No model.)

To all whom, it may concern:

Be it known that I, ADoLrHE BOURNIQUE, a citizen of France, residing atChesterton, in the county of Porter and State of Indiana, have inventedcertain new and useful Improvements in Machines for ManufacturingWindow- Glass, of which the following is a specification.

In the glass industry, and more particularly in the manufacture ofwindow and plate glass, large cylinders, and hollow bodies, considerableexpense is entailed in the' production of the class of merchandiseaforesaid by reason of their weight and bulk and the means generallyemployed for handling and manipulating the glass during the process ofmanufacture.

This invention has for its object to materially reduce the cost ofproduction, to lessen the manipulation by hand, to minimize the chancesof breakage, to facilitate the operation whereby frequent reheating ofthe glass is obviated, and to devise a machine for accomplishing all thesteps heretofore generally practiced by hand.

The machine comprises a ladle suspended from an overhead track andadapted to receive a quantity of molten glass from a tank, furnace, orother contrivance constituting the supply from which the glass is takenas used in the manufacture of the merchandise. A carrier mounted upon atruck is adapted to receive the ladle, and after the glass has beentaken up from the ladle the support for the truck drops, so as to removethe truck out of the way. The blowpipe, with the glass attached thereto,is connected to an iniiatingtube, by means of which the glass is blown.Means are provided for imparting a backward and forward rotary movementto the blow` pipe during the several operations in order to preventtwisting of the neck of the glass during the expansion thereof. Areheater forms an essential part of the mechanism for softening the bulbwhen the same becomes necessary. A former is provided to limit theexpansion of the bulb and insure the formation of articles ofpredetermined size. Actuating devices for controlling the movements ofthe working parts, including valves and operating means therefor, arenecessary adjuncts of the mechanism and are referred to in detail in thesubjoined description.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of moditication, still the preferred embodiment of theinvention is illustrated in thc accompanying drawings, in which- Figurel is a diagrammatic view of a mechanism embodying the invention. Fig. 2is a detail view of the pressure-tank, truck, movable platform for thetruck, the blowpipe, in'iiating-tube, valves, and supporting' means forthe several parts, the same being shown on a larger scale, the blowpipebeing connected to the inflating-tube and having the batch of glassattached thereto and partly eX- panded.

Fig. 25 is a top plan view of Lthe gripper for transferring theblowpipe from the mechanism initially acting upon 'the glass -to the'nishing mechanism.

Corresponding and 'like parts are referred to in the "followingdescription and indicated in 4all the views of the drawings by the samereference characters.

yThe overhead track is indicated at 1 and is supported byhangers 2 fromthe ceiling, beam, or rafter 3. Trolleys 4 and 5 are mounted 'to travelupon the track 1 and are adapted to hold, respectively, the ladle 6 andgripper 7 in suspension, "the latter being employed when transferring'the blowpipe from the initial expander 'to 'the mechanism forcompleting the'expans'ion of the glass and simultaneously vinparti'ng abackward and forward rotation thereto. lThe trolley 4 4is provided witha sleeve`8,suspended therefrom by means of the chain or analogousconnection `9 and adapted to receive the handle 1() of the ladle 6, saidFig. 15 is a topv handle being detachably connected with a lug at oneside of the ladle. The ladle 6 may be ofany size and construction, andis preferably of forged steel, and is adapted to snugly fit the carrier11 of the truck 12.

The tank 13 is adapted to receive the molten glass and may be a furnaceor reservoir such as commonly employed for receiving the refined glassto be worked and fashioned into the required merchandise. The ladle isintroduced through an opening 14 in a side of the tank or furnace whenit is required to obtain a quantity of glass, the weight of the ladleand material being suspended by the trolley 4 and track 1. The truck l2is moved upon the track 1.5 into convenient position to receive theladle 6 when withdrawn from the furnace or tank. After the ladle hasbeen snugly fitted in the carrier 11 the handle 10 is disconnectedtherefrom and the truck moved upon the track 15 away from the tank, soas to occupy a position on the platform 16 in vertical alinement withthe blowpipe 17. The platform 16 is counterbalanced by weights 18,fleXiby connected thereto by cables or chains 19, passed overguide-pulleys 20. The motor-cylinder 21 is connected with the platform16 to effect vertical movement thereof for raising and lowering thetruck 12. The

piston 22, arranged to operate in the cylinder 21, is connected with theplatform 16 to effect vertical movement thereof for raising and loweringthe truck 12. The piston 22, arranged to operate in the cylinder 21, hasits rod 23 connected to the platform 16 in anyI substantial manner tocause the parts to move in unison. Any desired medium may be employedfor actuating the piston 22, compressed air being preferred, and storedin a reservoir or tank 24. This pressure-tank 24 is provided with anytype of safety-valve 25 to relieve dangerous pressure and with a gage 26to indicate the number of pounds of air contained in the tank. Thedistributing-pipe 27 is connected with the pressure-tank 24, andbranches are coupled thereto for conveyance of the compressed air oractuating medium to various operating parts. The branch pipe 28 connectsthe distributingpipe 27 with the lower end of the motor-cylinder 21 andis provided with a valve A for controlling the admission of thecompressed air into the motor cylinder and the escape of the airtherefrom when no longer required for operation. The valve A may be ofany type so long as it enables the attainment of the desired end. Itispreferred to have the valve of the variety to be controlled by anelectric current, the same being operated by means of a switch-lever a,conveniently located upon the switchboard 29. In one position of theswitch-lever a compressed air is admitted into the motor-cylinder so asto elevate the plat- IOO IIO

form and support the truck in line with the track 15. In anotherposition of the switchlever a the supply of compressed air is shut offfrom the motor-cylinder and communication is effected between saidmotor-cylinder and the atmosphere to permit escape of the air confinedin the cylinder below the piston 22, thereby permitting the platform andtruck to descend, as indicated most clearly in Fig. 3.

A motor-cylinder 30 has its piston 3l connected to arms 32, 33, and 34by means of the rod 35, whereby the parts move together when travelingupward or downward. There are two arms 32, and they carry amotor-cylinder 36, in which operates piston 37. The arms 33 and 34 areconstructed at their outer ends to receive and support the blowpipe 17in the operation of the machine. Any suitable means may be applied tothe arms 33 and 34 for retention of the blowpipe, but yet admit of itsremoval by proper manipulation when required. Flexible tubes 38 and 39connect a branch pipe 40 of the distributing-pipe 27 with valves B andC, connected, respectively, with the opposite endsof the motor-cylinder36. These valves B and C are similar in construction to the valve A andare electrically controlled by means of the switch-lever which ismounted upon the switchboard 29. In one position of the switch-levercompressed air is admitted intoone end of the motor-cylinder 36 andexhausted from the opposite end, whereby the piston 37 is positivelyactuated in one direction. In another position of the lever b thecompressed air is admitted into the opposite end of the motor-cylinder,so as to elfect positive movement of the piston 37 in a reversedirection, the parts being so disposed that as the compressed air entersone end of the motor-cylinder the air in the opposite end is exhausted,thereby obviating cushioning of the piston. A cylinder 41 is attached toor forms a part of the motorcylinder 36 and receives the inflating-tube42, which fits within the cylinder 41 steam-tight. The iniating-tube 42is connected to the rod 43 of the piston 37 and is provided intermediateof its ends with an annular groove 44, in communication with the bore orspace of the tube by a series of openings 45. rI`he lower end of theinflating-tube is closed by a packing 46, which is adapted to make aclose fit with the rounded end 47 of the blowpipe 17 when the two areconnected. The pipe 48 connects with the cylinder 41 at a point near thelower end thereof, so that when the inflating-tube is at its lowestposition the annular groove 44 is in register with the pipe 48, therebypermitting air to pass therefrom into the tube and thence into theblowpipe. The pipe 48 connects with a pressure-reducer 49, which isconnected with a distributing-pipe 27 and which reduces the pressure ofabout eighty pounds to about two ounces, thereby admitting of gentle andslow expansion of the glass 50.

f The motor-cylinder 30 has its lower end connected by branch pipe 51with the distributing-pipe 27, and the compressed air is regulated bytlie valve D in the length of the pipe 51 and adapted to be controlledby the switchlever d, mounted upon the switchboard 29. When theswitch-lever Z is moved to one position, the piston 31 and rod 35 aremoved upward, carrying the motor-cylinder 36 and blowpipe 17 therewith.When the valve D is moved to the opposite position, the air is permittedto exhaust from the cylinder 30 below the piston 31, thereby permittingthe latter and the parts controlled thereby to gravitate and theblowpipe to descend into the ladle, so as to receive the glasstherefrom. After the blowpipe has entered the ladle and the glassbecomes attached thereto the switchlever d is moved so as to operatevalve D and admit air into the cylinder 30 below the piston 31, wherebysaid piston and blowpipe are elevated to the position about as shown inFig. 2. This operation elongates the glass and forms the neck. The levera is now operated to actuate the valve A, so as exhaust the air from themotor-cylinder 21, thereby permitting the platform and truck to descendout of the way. The switch-lever is now moved to operate valves B and Cto admit compressed air above the piston 37 and to exhaust the same frombeneath the piston, thereby permitting downward movement of thel pistonand infiating-tube. Then the in- Hating-tube 42 is at its lowestposition, it makes close connection with the blowpipe, and at the sametime communication is establishedv between the inflating-tube and thesupply branch 48, when the air passing into the inflating-tube isdirected into the blowpipe and the glass 50, gradually expanding thelatter, as indicated most clearly in Fig. 3. After the glass 50 has beenexpanded to form a bulb of required size the lever is again operated toactuate valves B and C to effect upward movement of the piston, therebydisconnecting the iniiating-tube 42 from the blowpipe and at the sametime shutting off the supply of air to the iniiating-tube, the latteracting in the capacity of a cut-off. At this stage of the operation thegripper 7 is brought into play and takes hold of the blowpipe 17, andupon the application of suiiicient force the blowpipe is disconnectedfrom the supporting-arms 33 and 34 and is transferred to the finishingmechanism, by means of which the blowpipe is rotated backward andforward, the glass bulb being reheated, elongated, shaped, and cooled.

The expanding mechanism employed in the second step of the operation isa duplicate of IOO IOS

IIO

that employed `in the lirst step. Hence a detailed description thereofis not deemed necessary, corresponding parts being designated by thesame reference characters.

Arms 33ll and 34E, corresponding to the arms 33 and 34, are attached toan upright 52 and receive and support the blowpipe 17 in the finishing'operation. The arm 34 is extended in an opposite direction and supportsa motor 53, by means of which the blowpipe is operated. The motor 53 ispreferably of the electric variety and is connected by conductors to arheostat circuit-closing lever 54, which admits of controlling themovement of the motor, as may be required. The means for closing themotor-circuit are conveniently located to the switchboard 29 and, asshown, comprise a circuit-closing switch and the rheostat-lever. Thepower-transmitting means comprise the shaft 55, having worm-thread 56and gear-wheel 57, a pinion 58, secured to the motor-lever and in meshwith the gearwheel 57, worm-gear 59, in mesh with the worm-thread 56,gear-wheel 60, connected by pitman 6l to worm-gear 59, idle pinion 62,in mesh with the teeth of the gear-wheel 60, and the pinion 63, formingla part of or applied to the blowpipe. The gear-wheel 60 and pinion 62are journaled to pins applied to the arm 33, and the cogs are inclined.As shown most clearly in Fig. 12, the upper portion of the blowpipe isof larger diameter, and the pinion 63 is located at the juncture of thelarge and small portions and is preferably an integral part of theblowpipe, being' upwardly flared, thereby serving as a stop-shoulder tosupport the blowpipe when the machine is in operation. rlhe upper sideof the arm 331L is provided with a conical seat 64 to receive thetoothed portion 63 of the blowpipe and support the same against verticaldisplacement. After the blowpipe 17 has been placed in position it dropsslightly to enable the part 63 to enter the seat 64E and to mesh withthe teeth of the pinion 62. The pitman 61 is connected to thegear-wheels 59 and 60 at different distances from their centers, so asto insure an oscillatory movement of the gear-wheel essential to imparta backward-and-forward movement to the blowpipe in the final steps offinishing the article.

The reheater is indicated at 65 and comprises similar halves or sectionshinged together in line with the upright 52, which preferably passesthrough hinged lugs projected from the sections or parts of the heater.By having' the reheater composed of sections mounted in the mannerstated they are adapted to readily close around the glass bulb and toopen out of the way thereof` when said bulb is sufliciently softened.Thereheater may be of any structural type so long as it subserves thepurpose of softening the glass. Itis preferred to have each of thesections made hollow and to have the inner wall studded with openings,as indicated at 66, through which the llame has access to the glass. Thelower end of the heater is open to admit of observing the lower' end ofthe bulb when elongated to the requisite degree. An observation-slot 67is formed in a side of the heater and admits of inspecting the glassbulb at all times during the process of reheating and expansion. Aflexible tube 68 connects the upper end of each section of the reheaterwith the distributing-pipe 27 An arm 69 projects from the upright 52 andsupports a carriage 70, which is provided at opposite ends with restsfor receiving' the iiexible tube 68. A rod or bar 71 is pendent from thecarriage 70 and constitutes a hanger and is .connected with links 72 andpiston-rod 73 at their point of liuncture. The links 72 are looselyconnected to the sections of the reheater in such a manner as to effectan opening and a closing thereof according as the piston-rod 73 isthrust outward or moved inward. The pipe 74E conneets with a suitablesource of gas-supply and is in communication with the flexible tube 68and is driven forward into the space of the reheater-sections andthrough the openings 66 by the blast of air derived from the pipe 27. Avalve 75 is provided for controlling the supply of air and gas to thereheater and is connected with the operating means employed for openingand closing the sections of the reheater, so as to be simultaneouslyoperated therewith. Vhen the sections of the reheater are closed, thevalve 75 is opened to its fullest extent, thereby admitting of thepredetermined supply of air and gas being admitted to the reheater; butwhen the sections of said reheater are open the valve 75 is closed, ornearly so, thereby permitting a minimum amount of gas being supplied tothe reheater for maintaining the same heated and preventing coolingthereof. As shown, a lever 76, fulcrumed at 77, has its lower endconnected to an arm of the valve 75 and its opposite end connected tothe hanger 7l or connecting means between said hanger and the pistonrod73.

A motor-cylinder 78, similar in construetion to the motor-cylindersherein described. is horizontally arranged, and the piston-rod 73 andits piston are connected to the links 72 and lever 76 in any way. ValvesE and F are connected to opposite ends of the motorcylinder and to thedistributing-pipe 27 by means of flexible tubes 79 and 80. The valves Eand F operate in substantially the same manner as the valves B and C andare adapted to be controlled by the switch-lever e, which in oneposition operates the valves to admit air into one end of the cylinderand to exhaust it from the opposite end and in another IOO IIO

position reverses said valves so as to drive the piston of themotor-cylinder 78 in an opposite direction. Vhen the piston-rod 73 ismoved outward, the sections of the reheater are closed, and when thepiston-rod is moved into the cylinder 78 said reheater-sections areopened.

The former for giving the required shape to the finished article is ofmetal lined with paste and is constructed of sections outwardly flangedand. secured together by fastenings passed through openings of theflanges. The former is indicated at 81 and is open at its upper end andclosed at its lower end and is connected to the rod 82, coupled to orforming an extension of the rod provided with the piston 83, arrangedwithin the motor-cylinder 84. After the glass bulb has been expanded andelongated the former 81 is moved upward so as to envelop the bulb andgive the predetermined shape thereto, as indicated most clearly in Fig.7. The piston 83 is moved in the cylinder 84 by means of compressed airderived from the distributing-pipe 27 and controlled by valves G and H,constructed and operating in a manner similar to the valves controls thevalves G and H to admit the air at one end of the cylinder and providean es-v cape for the confined air at the opposite end.

The cooler 85 consists of a tank and is located so as to receive theformer 81 when at its lowest position. The cooler is maintained at theproper temperature by water supplied thereto by means of the pipe 86,the warm water passing off by way of the pipe 87 and discharging at anyconvenient point. The cool water enters the lower portion of the tank85, whereas the warm water passes off from the upper end. k

The arms 33 and 33n are constructed substantially alike, each having itsouter end forked and the outer ends of the fork members iared to directthe blowpipe into the crotch. The seat 64 is formed in the upper side ofthe arm at the inner end of the crotch. The arms 34 and 34(l have theirouter ends constructed similar to the outer ends of the arms 33 and 33uand have the jaws formed with lateral openings in which the dogs orgrippers 88 are located, the inner ends of said dogs being adapted toclose in front of the blowpipe and retain the same in place, asindicated most clearly in Fig. 16. Flat springs 89 carry the grippers 88and are attached to opposite sides of the arms by suitable fastenings.The gripping ends of the elements 88 are constructed to admit of thegrippers being forced apart upon the application of sufficient force tothe blowpipe when placing the same in position or removing it from thearms.

In practicing the invention the ladle 6, suspended from the trolley 4and track 1, is maforward.

nipulated by hand and introduced into the opening 14 of the tank 13-andreceives a quantity of molten glass, after which the ladle is withdrawnand deposited upon the truck 12, which is run out upon the track 15 ontothe platform 16. The switch-lever CZ is now operated to permit theblowpipe 17, carried by the arms 33 and 34, to descend into the ladle,so as to take up the glass. is again operated to admit air into thelower end of the motor-cylinder 30, whereby the blowpipe, with theglass, is carried upward and the lever a is yoperated to permit theplatform and truck to descend out of the way, after which the lever ismoved to cause the inflating-tube 42 to descend and make connection withthe blowpipe and to establish communication between the inflating-tubeand the air-pipe 48. The glass attached to the blowpipe is graduallyexpanded to form the bulb 50, and after the same has attained thedesired size the lever b is again operated to cause upward movement ofthe inflating-tube to disconnect it from the blowpipe and toshut off theblast by means of which the'bulb is formed. The gripper 7 is broughtinto operation at this stage and takes hold of the blowpipe andtransfers the same from the arms 33 and 34 to the arms 33'and 34,whereby said blowpipe is connected with the oscillating mechanism. Uponmoving the lever 54 the motor 53 is set in operation and through theconnections herein described causes the blowpipe to rotate backward andThe lever e is moved to effect a closing of the sections of the reheater65 about the bulb 50, so as to soften the same, and the lever isoperated to cause the iniiating-tube 42 to make connection with theupper end of the blowpipe, whereby the bulb is expanded simultaneouslywith its softening. When the bulb is elongated to the required extent,the lever e is again operated to cause opening outward of thereheater-sections, and at the same time the lever g is moved to effectupward movement of the former 81, so as to envelop the bulb and give thedesired shape thereto. After the bulb has been shaped the lever g isagain moved to cause the former to descend into the cooler 85, and thelever b is moved to cause upward movement of the inflating-tube anddisconnection thereof from the blowpipe. rlhe cylinder thus formed istransferred to a stand, and the ends are cracked off and the cylindersplit longitudinally and transferred to a table, upon which it opensflat to form window or plate glass.
